A major search was launched for 24-year-old Miss Buckley, from Cork, when she was reported missing from the flat she shared with friends after failing to return home from a nightclub in Glasgow's west end in April this year.

Her body was found days later at a farm on the outskirts of the city.

Miss Buckley, a nurse who was studying for a post-graduate qualification at Glasgow Caledonian University, was seen on CCTV leaving The Sanctuary nightclub in the early hours of Sunday April 12 and the footage captured her talking to a man as they walked along Dumbarton Road.

Detectives soon said they were treating her disappearance as a high-risk missing person inquiry and her parents also flew over from Ireland.

By the Tuesday, police revealed they had spoken to the man seen talking to Miss Buckley outside the club who had said she travelled with him to his flat a few miles away in Dorchester Avenue before leaving some hours later.
